Aeromotive Compact EFI Fuel Pressure Regulator

Aeromotive regulators beat the competition with the best of all worlds:
Outstanding, consistent performance from equipment that’s built to
last.
Aeromotive delivers more flow than similar regulators thanks to a
custom, convoluted diaphragm that maximizes piston stroke while
minimizing stress. Every model uses a poppet designed specifically for
that regulator, and a diaphragm fabricated from a proprietary elastomer
material. The standard vacuum boost port delivers perfect 1:1 boost
reference and makes these regulators ideal for turbo-charged and
supercharged engines.
